In this project we will be interfacing HX711 Load cell amplifier with Arduino and 16*2 LCD for designing Arduino Weighing. JohnRob July 21, 2021, 2:03am #3. Yes, In general. Each load cell is designed to output more or less the same signal for 100% load. So a 100g load cell and a 500kg load cell will both put out the same signal at their maximum load. That said you have to look at the 500kg load cell specification and see if it is appropriate to use the HX711.

The first step is to test the low end of the weight scale and you can do this without adding load to the load cell. So the variable loadLow in Arduino sketch code can be assigned 0 as for zero grammes. Then copy the smoothed analogue value to the analogLow variable and move on to the next step Apply pressure to the load cells (all of them at once) and observe a change in the voltage between A+ and A-. Assuming that is showing good results (the voltage change will be quite small, so set your DMM to its most sensitive setting), your next point of call is the connection to the Arduino itself
